I got a 1" x 1/8" x6" piece of o1. Put about a 30 degree angle in it and a 10 degree bevel. Heat treated and tempered then sharpened and polished to 8,000. It shaves and skives about 3/16" wide but I am having trouble doing any sort of wide skive I could fold. I can tell it likes to slice at an angle greater than 30 degrees. I think my bevel is too small and the steel is too thick. I will mess with it more. I can tell it will take a lot of tinkering to figure out. Good news is I think I will make a trim knife since the knife making part was easy enough. Took up most of an evening but it was educational. The tip got nicked a so I can see how rounding that would be useful, wont really be cutting with that part anyway.
